Don't put "he" or "she" at the begginning of every single descriptive or action sentence; "She closed her eyes. She was worried about gettting caught, blah blah blah." Boring!Try this: Sqeezing her eyes shut, she retreated to the solace of the darkness. It would all be all right; she told herself. That is, provided she wsn't caught on the way there."

When writing dialogue, it's also important to take into mind who the character is talking to. Padme addresses the Senate in a proffessional way, where as she adresses Anakin in a casual way or a romantic way. ie;"Ladies and gentlemen of the senate, I beseech you..." vs."Oh, Anakin,where have you been? I've missed you so much..."

STAY IN CHARACTER! When writing known characters, stay in character. Watch the movies, read the books. Research them for as long as it takes you to be able to sit down and write them as naturally as you could your best friend.

Actually, yes, you are. Not necessarily dialogue that would sound natural if you said it to your friends, but dialogue that fits the universe and characters. A soldier probably won't sound like a holostar won't sound like a Jedi; Dooku won't talk like Anakin and neither of them like Yoda; and it is very unlikely that any of them should sound like Buffy the Vampire Slayer.

Sometimes is helps to just sit down and write with out thinking. It doesn't have to be star wars, it can be the most random thing in the world, but it gets your mind moving and thinking. As soon as you stop to think, don't keep writing what you have been, go back to writing your story.

Imagination is a key ingredient to fanfic. If you can thinnk of it, you can write about it. The problem that some people may have is visualizing it. Visialization can help with a battle sequence, lightsaber duel, or other scenarios.

Have a basic setting in mind, then try to sketch it out on paper. This works well for close combat situations, where you can look at your 'map' for reference. It also allows you to free up a bit of your mind to focus on other things. Plot out where the characters will be on your map and the directions that they will go. Planning ahead can help with ideas of what they will use and moves they will make.

Try not to make an orignial character (especially a girl) a Mary Sue. I've done that once or twice and suffered for it. I've since then learned all the aspects of the Mary Sue and have strived not to make any of my female OC characters one of them.

I absolutely adore OCs, but am not too keen on Mary Sues. Neither are many other people.
